Answer: Selectively permeable means a membrane allows the passage of some molecules or ions and inhibits the passage of others. The capacity to filter molecular transport in this manner is called selective permeability.
Explanation:
Shortened: This means the membrane only allows some things to pass through while others can't.

Based on respiratory function tests, the correct options are:
- spirometer.
- vital capacity
- residual volume.
<h3>What is a respiratory function tests?</h3>
A respiratory function test is a test done to evaluate the ability of the lungs to take in air and remove carbon dioxide
The machine used for this test is called a spirometer.
Therefore;
- Ms. L's respiratory function was evaluate using a machine called a spirometer.
- The amount of air that can be expelled by maximum ex-halation after maximum inhalation is termed the vital capacity
- An increase in the amount of air remaining in her lungs after a normal expiration is called the residual volume.

Answer:
1/8 (12.5%)
Explanation:
An autosomal recessive disease is an inherited disease in which an individual need to receive both defective alleles at the same gene <em>locus</em> to be expressed in the phenotype. In this case, both parents are carriers of the recessive mutant allele associated with the sickle cell anaemia trait, thereby both parents are heterozygous, ie., each parent has one copy of the normal allele 'H' and one copy of the defective mutant allele 'h' associated with this condition. In consequence, their first child has a 1/4 (25%) chance of having sickle-cell anaemia. Moreover, the chance of having a girl is 1/2 and the chance of having a boy is 1/2, thereby the final chance of having a girl sickle cell anaemia individual is 1/4 x 1/2 = 1/8 (12.5%).
- Parental cross for sickle cell anaemia trait = Hh x Hh >>
- F1 = 1/4 HH (normal); 1/2 Hh (normal); 1/4 hh (sickle cell anaemia) >>
- Sex proportion of sickle cell anaemia individuals = 1/8 female sickle cell anaemia individuals + 1/8 male sickle cell anaemia individuals (1/8 + 1/8 = 1/4)
